NEW YORK (AP) — Alex Rodriguez faces a new challenge: He is being sued by his own lawyer.

Attorney David Cornwell's law firm filed papers Monday in Manhattan federal court saying the New York Yankees star owes more than $380,000 related to their work fighting his steroid suspension.

As first reported by The Daily News, the firm also is seeking pre-judgment interest and attorney fees that could increase the amount to half a million dollars.

Rodriguez spokesman Ron Berkowitz released a statement on the suit: "Alex Rodriguez has already paid substantial legal fees to this firm. There are no additional fees being sought from hours that continued to be billed and are the source of the disagreement between the parties. Alex looks forward to swiftly resolving this matter and moving on.''

Rodriguez was suspended for the 2014 season as a result of a drug investigation by Major League Baseball. He has said he plans to rejoin the Yankees in 2015.

Rodriguez has admitted that he used performance-enhancing drugs from 2001-03 but has denied using them since.
